概要 （英文）

In this paper,a conceptual design of LNG fuel CO2 recovery type thermal power generation system is performed and that economics is evaluated.The outline of proposed system is as following.After fuel gas is reformed,hydrogen and carbon mono-oxide etc.gasare sepalated,latter gas is combusted at reformer with pure oxigen,and high concentration CO2 is exhausted directly and liquidized.Based on prooven technologies,two types CO2 recovery systems using defferent types hydrogen separation facilities,one is ahydrogen separation membrame,the other is a pressure swing hydrogen adsoption(H2 PSA)are studied and compared.As a result,both systems are feasible using prooven technologies.With respect to economics,the hydrogen separation membrane system has a same electricity cost as a CO2 recovery system from an exhaust gas of LNG combined cycle power generation system.
